Asher - Not the tribe so called, but a place somewhere toward the eastern end of the boundary line here drawn: perhaps “Teyasir,” on the road from Sichem to Beth-shean.
Matthew Henry
Concise Bible Commentary
There was great communication between Manasseh and Ephraim. Though each tribe had its inheritance, yet they should intermix one with another, to do good offices one to another, as became those, who, though of different tribes, were all one Israel, and were bound to love as brethren. But they suffered the Canaanites to live among them, against the command of God, to serve their own ends.
